Embodiment

[0035] A multi-node vehicle control system based on the FSAE electric formula racing car disclosed in this embodiment is as follows: figure 2 As shown, it consists of six main parts: front cabin acquisition ECU1, panel interaction ECU15, vehicle control ECU6, vehicle isolation CAN bus 5, main switch 7, and power module 8.

[0036] Such as image 3 As shown, the front cabin acquisition ECU1 includes: a first regulated power supply chip, a front cabin main control chip, and a first isolated CAN module chip.

[0037] The first regulated power supply chip converts the 12V power input from the power module 8, and the first regulated power supply chip includes a regulated power supply chip modeled as MP1484 and a regulated power supply chip modeled as AMS1117. The MP1484 regulated power supply chip outputs 3.3V power supply for the front cabin main control chip and the first isolated CAN module chip, and the AMS1117 regulated power supply chip outputs 5V power supply for the brake...

Abstract

The invention discloses a multi-node vehicle control system for a small racing car. The multi-node vehicle control system comprises a front cabin acquisition ECU, a panel interaction ECU, a vehicle control ECU, a vehicle isolation CAN bus, an accelerator angular displacement sensor, a steering wheel angle sensor, a front wheel speed sensor, a braking angular displacement sensor, a mode control knob, a high-voltage closing button, a motor enabling button, a buzzer, a brake lamp and a drive system indicator lamp. The control system uses the vehicle isolation CAN bus for receiving and sending data, multiple CAN nodes are adopted so that wiring harnesses can be effectively reduced, and data acquisition and processing are more convenient and efficient; meanwhile, the multiple ECUs are adopted, each ECU can achieve data acquisition, human-computer interaction and vehicle control functions, the purpose that multiple tasks are conducted at the same time is achieved, the response speed is increased, and stability is improved; and by the adoption of the control system, a control program is more convenient to write and debug, and the system is more suitable for the FSAE pure electric formula racing car.
